如何使用 CURL PHP 从 Google Business 获取评论

Question

我正在尝试在 Google Business 中获得评论。目标是通过curl获取访问权限，然后从pane.rating.moreReviews标签jsaction获取值。

如何修复下面的代码以获取curl？

function curl($url) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.94 Safari/537.36');
  $html = curl_exec($ch);
  curl_close($ch);
  return $html;
}

$html = curl("https://www.google.com/maps?cid=12909283986953620003");
$DOM = new DOMDocument();
$DOM->loadHTML($html);
$finder = new DomXPath($DOM);
$classname = 'pane.rating.moreReviews';
$nodes = $finder->query("//*[contains(@jsaction, '$classname')]");
foreach ($nodes as $node) {
  $check_reviews = $node->nodeValue;
  $ses_key = preg_replace('/[^0-9]+/', '', $check_reviews);
}

// result should be: 166
echo $ses_key;

如果我尝试做var_dump($html);，我会得到：

string(348437) " "

而且这个数字在每次页面刷新时都会发生变化。

? 使用 PHP cURL 和没有 API 密钥获取 Google 评论

如何查找 CID - 如果您在 Google 地图中开设了公司：

• 在 Google 地图中搜索商家名称
• 确保它是唯一显示的结果。
• 将 URL 中的 http:// 替换为 view-source:
• 点击 CTRL+F 并在源代码中搜索“ludocid”
• CID 将是“ludocid\u003d”之后的数字，直到最后一个数字

或使用此工具：https://ryanbradley.com/tools/google-cid-finder/

示例

ludocid\\u003d16726544242868601925\

提示：使用 CSS 中的“.quote”类来设置输出样式

PHP

=====================================================

How to find the CID - If you have the business open in Google Maps:
- Do a search in Google Maps for the business name
- Make sure it’s the only result that shows up.
- Replace http:// with view-source: in the URL
- Click CTRL+F and search the source code for “ludocid”
- CID will be the numbers after “ludocid\\u003d” and till the last number

or use this tool: https://pleper.com/index.php?do=tools&sdo=cid_converter

Example
-------
```TXT
ludocid\\u003d16726544242868601925\
```

> HINT: Use the class ".quote" in you CSS to style the output

请尝试以下代码

$html = curl("https://maps.googleapis.com/maps/api/place/details/json?cid=12909283986953620003&key=<google_apis_key>", "Mozilla 5.0");
$datareview = json_decode($html);// get all data in array

例如：http://meetingwords.com/QiIN1vaIuY

它会为你工作。
